  • "A full-scale crash test was performed to evaluate the impact performance of a Texas T223 concrete beam and post bridge rail anchored to a 5-inch cast-in-place deck (CIPD). The testing followed the MASH standards for Test Level 3 (TL-3) longitudinal barriers. The test performed was American Association of State Highways and Transportation Officials (AAHSTO) Manual for Assessing Safety Hardware (MASH) test 3-11, which involves a 2270P (5000 lb) pickup truck impacting the critical impact point (CIP) of the barrier at a nominal impact speed and angle of 62 mi/h and 25 degrees, respectively. This test evaluated the strength of the barrier and its anchorage to the 5-inch CIPD. The T223 bridge rail anchored to a 5-inch CIPD successfully met all required MASH evaluation criteria. The rail anchorage withstood the design impact without any visible distress. The rail anchorage detail is considered suitable for implementation when concrete bridge rails are attached to 5-inch decks cast on prestressed box and slab beams. The anchorage detail is considered acceptable for use with the T223 bridge rail, other concrete bridge rails, and metal rails mounted on concrete parapets."
